Air Nozzles


What is an Air Nozzle?
An Air Nozzle is a simple low cost solution to diminish noise levels and more importantly save you money by reducing excessive air consumption on compressed air blowoff operations. They are ideal for anything from multi-unit nozzle manifolds for conveyorized products of transfer lines to your standard hand-held blowoff gun.

Why Air Nozzles?
Replace open copper tubes, pipes and plastic nozzles with STREAMTEK Air Nozzles and compressed air savings can be as high as 80%! The less compressed air that is used essentially means less noise. Noise reduction up to 10-15 dBA is typical. Ohh and yes, did we mention that our Air Nozzles meet Occupational Safety and Health Administration (OSHA) maximum dead ended pressure requirements?

Did you know?
Air Nozzles Copper TubeA 1/4″ (6mm) open ended copper tube will output up to approximately 40 SCFM (Standard Cubic Feet per Minute) – 1133 SLPM! This is equivalent to the total output of an 8-12 horsepower air compressor. The static pressure requirements set by OSHA will be compromised when the supply pressure of an open pipe, tube and/or drilled holes surpasses 30 PSIG (2 BAR). In addition, the noise levels will often reach well above 95 dBA. STREAMTEK Air Nozzles & Air Jets address all of these issues!


Air Nozzles are the smallest amplifiers for precise point type applications. If a larger blowoff area is required, our Air Jets are the more efficient choice! Click here for information relating to STREAMTEK Air Jets.

(A) Compressed air enters the Air Nozzle via a standard MNPT inlet

(B) As the compressed air moves through the nozzle, the surrounding air is entrained over a precision engineered designed profile surface. This action is called the “coanda effect”.

(C) The compressed air in combination with the entrained air results in a high volume, high velocity, laminar airflow stream of amplified air (25 times or more) with maximized force.


STREAMTEK Air Nozzles produce more power at a fraction of the cost of open air lines, tubes or jets. If you don’t find a solution and/or idea for your application, or if you want additional details, call our factory at 1-705-770-4455 or email an Application Engineer at

Below is a list of Frequently Asked Questions relating to our Air Nozzles. If you need additional help with your application and/or can’t find an answer to your question, please call our factory at 1-705-770-4455 or email an Application Engineer at
1. Are STREAMTEK Air Nozzles OSHA safe?

Yes. Our Air Nozzles meet OSHA standard CFR 1910.242(b) for dead end pressure. In addition, noise levels are significantly reduced with our Air Nozzles.

2. What is the material of STREAMTEK Air Nozzles?

Our Air Nozzles are available in four materials (Aluminum, Brass, 303 Stainless Steel and 316 Stainless Steel). Zinc & PEEK Plastic Air Nozzles can be manufactured upon special request.

3. What are the temperature limits for your Air Nozzles?

Aluminum for temperatures up to 275°F (121°C)
PEEK for temperatures up to 320°F (160°C)
303 Stainless Steel for temperatures up to 400°F (204°C)
316 Stainless Steel for temperatures up to 1000°F (538°C)

4. Will STREAMTEK Air Nozzles replace an open air line with identical effectiveness?

Both the dead end pressures and noise levels of an open air line pose a very serious safety issue! Our Air Nozzles will provide noise reduction up to 10 dBA as well as reduced air consumption when compared to open lines, tubes and jets. All this is done while maintaining OSHA-mandated dead end pressure levels.

Due to the significant reduction in compressed air consumption, STREAMTEK Air Nozzles may not always provide the 1:1 blow-off force as an open air line operating at same supply pressures. With that said, there are many applications that will not require the high force of an open air line. If you need a higher force, we can provide larger Air Nozzles that will produce the required force and still comply with OSHA standards.
